Philips FY2422/30 or Dyson 965432-01: which filter is the smarter buy?

Display

This category is not really applicable in the usual sense, because these are replacement air filters rather than standalone devices with screens. If you’re judging by how clearly they integrate with the purifier’s display and filter-life indicators, both are designed to work with their respective machines rather than offer their own interface. Winner: tie. There is no meaningful difference in display quality between a Philips replacement filter and a Dyson replacement filter.

Performance

On pure filtration performance, both are strong and both carry a 4.6/5 rating, but they are optimised for different purifiers. The Philips FY2422/30 is a NanoProtect HEPA replacement for Philips 2000i and 3000i series machines such as AC2887, AC2889, AC2892 and AC3829, with a stated 24-month lifetime. That longer lifetime is a major advantage for UK households dealing with year-round dust, spring pollen, and damp-season mould spores, because it means fewer replacements and lower annual hassle. Dyson’s 360° Glass HEPA + Carbon Filter is also a genuine high-quality replacement, but its value depends on owning one of the supported Dyson models (DP04, HP04, HP07, HP09, HP10, PH03, PH04, TP07, TP09). In practice, the winner is Philips for most buyers because it offers the same strong review score, a longer stated service life, and a lower cost for comparable day-to-day air cleaning performance when paired with the right machine.

Build quality and design

Dyson wins here on perceived engineering and premium construction. The 360° filter format is designed to work around Dyson’s cylindrical airflow architecture, and Dyson’s replacement parts generally feel more integrated into the machine’s overall design language. That said, Philips is no slouch: the FY2422/30 is an original replacement filter, and the 24-month lifetime suggests a robust media pack intended for sustained use. In practical terms, build quality matters less than fit and filtration media, and both are genuine OEM parts. Winner: Dyson, but only narrowly, because the design is more premium and the filter is purpose-built for Dyson’s distinctive airflow system.

Battery life

Neither product has a battery, so this category does not apply. For air purifiers, the real equivalent is filter lifespan, and that is where Philips has the edge with a stated 24-month lifetime. Dyson does not have the same clearly stated lifespan in the product title here, so from an ownership-cost perspective Philips is the easier filter to budget around. Winner: Philips.

Price and value for money

This is the clearest category and the biggest reason to choose Philips. Product A costs £48.69, while Product B costs £79.99, a difference of £31.30. Both are rated 4.6/5, but Philips is significantly cheaper and has a stated 24-month lifetime, which makes it the better value on a cost-per-month basis. For UK buyers trying to keep a purifier running through pollen season, autumn damp, and winter heating months without overspending, that price gap is hard to ignore. Winner: Philips, decisively.

Game library/features

These are filters, not entertainment devices, so there is no game library. If we translate this category into features, the relevant comparison is compatibility and ecosystem support. Dyson’s filter is only for a defined set of Dyson purifiers, while Philips FY2422/30 fits a broad group of Philips 2000i and 3000i models. That wider compatibility is a practical feature because it makes the Philips option easier to identify and repurchase for households that already own one of those machines. Winner: Philips.

Overall user experience

User experience for replacement filters comes down to three things: easy buying, confidence it will fit, and not feeling ripped off every time you replace it. Philips scores best here because it is cheaper, has a long 24-month lifetime, and is backed by a huge review base of 1,693 ratings, suggesting many more real-world purchases and a well-established supply chain. Dyson still delivers a premium experience for existing Dyson owners, and its 333 reviews are also strong, but the higher price makes it harder to recommend unless you specifically need the Dyson-compatible part. For a UK household, especially one managing hay fever in spring or damp-related indoor air quality in winter, the lower running cost matters because filters are not a one-off purchase. Winner: Philips.

Overall summary: if you own a compatible Philips 2000i or 3000i purifier, the Philips FY2422/30 is the better buy for almost everyone. It matches Dyson’s review score, costs £31.30 less, and offers a stated 24-month lifetime that improves long-term value. Dyson’s filter is the right choice only if you own a supported Dyson purifier and want the original part made for that exact system. Otherwise, Philips is the smarter, more economical recommendation.
